1 all whom it may concern:

Be it known that I, CHAnLns F. DERRY, a citizen of the United States, residing at Adair, in the county of McDonough and State of- Illinois, have invented a new and useful Stock-Watering Device, of which the following is a specification.

This invention has reference to stock watering devices, and its obj eet is to provide means whereby a constant level of water may be maintained in drinking troughs for stock irrespective of the level of water in the supply tank or other reservoir, or of variations of such level.

In accordance with the present invention a drinking trougli, or several drinking troughs, are located at convenient points and a float valve control is provided with the float valve contained in a compartment separated from that from which. the stock drinks, with division means so arranged as to prevent liability of dirt which may get into the drinking trough from reaching the float box to interfere with the operation of the float.

The invention is particularly useful in connection with drinking troughs used for hogs, although it is also useful for watering other stock.

The invention will be best understood from consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings :Figure 1 is an elevation with parts in section showing a watering trough system arranged in accordance with the present invention. Fig. 2 is a plan view of the valve casing and float. Fig. 3 is a longitudinal section of the valve casing and float together with the valve and showing the float arm in large part in elevation and likewise showing the float in elevation.

Referring to the drawings there is shown a reservoir 1 which may be considered as in the form of a tank of relatively large capacity or any container for a supply of water.

The reservoir 1 is shown in the drawings as mounted upon a support 2, which support may be considered as of any convenient height, since the reservoir 1 may be either supported near the ground or on top of a tower asthe degree of elevation of the reservoir may vary greatly without material of feet upon the controlling means of the present invention.

Within the reservoir 1 is a pipe 3 continued over the top of the reservoir, and then downwardly, and this pipe may be conveniently supported by a bracket 4 fast to the outside of the tank or reservoir 1. The pipe 3 within the reservoir is continued therein to near the bottom of the reservoir where it may be surrounded by some pervious-material represented at 5 to serve as a strainer.

The down run of the-pipe 3 may be as long as needed and may have one or more branches 6 extending laterally to any desired extent.

In Fig. 1 troughs 7 are shown and are assumed to be located where needed and to be substantially alike. In each trough is a compartment 8 which for protection is shown as provided with a cover 9. The pipe 3 where a compartment 8 is in line with the vertical run of the pipe may enter such compartment through the cover 9 and such an instance is illustrated in Fig. 1. Furthermore, each branch pipe 6 where there is more than one branch pipe, may lead to another compartment 8 in another trough 7. The showing of Fig. 1 is deemed to be sufficient to indicate the multiplication of the device which may be carried out in an installation employing the present invention as a part of it.

At the end of the pipe 3 or of each branch pipe 6 is a valve casing 10 terminating in a valve seat 11 to which is adapted a valve 12 on one end of a valve stem 13.

The valve seat has formed on it or attached to it arms 14E between which there is pivoted a lever 15 by means of a pivot pin 16. The lever 15 is shown as a lever of the first order, and has a short arm connected by a pivot 17 to a block 18 carrying the valve stem 13. The other end of the lever is formed into an eye 19 traversed by a threaded stem 20 at one end of which stem there is secured a float 21. Nuts 22, 23 which may be conveniently of a type permitting ready manipulation by hand and without the aid of tools, provide for the securing of the float 21 to the lever 15 at different distances from the e er. T e

float 21 is shown as of double conical form with the bases of the cones in abutment. It is particularly advantageous to have one cone, indicated at 24,.with its apeX directed toward the bottom of the compartment 8, so that in the event of accumulation of mud within the trough 7, and such mud finding access to the compartment 8, the float presents so small a surface to contact with the mud as to avoid any liability of sticking which might occur should for any reason the water level drop to a suflicient extent. If sticking did occur water would flow into the trough 7 from the reservoir and so overflow the trough because of the failure of the valve to close.

The compartment 8 empties into the trough 7 by way of openings 25, each of which is provided with a shield 26 which may be formed by a partially punched out portion of the corresponding wallvof the compartment bent away from the compartment in a manner to shield the opening 25 from admission of mud into the compartment 8.

The bent pipe 3-acts after the manner of a siphon, since one branch of the pipe enters the water in the reservoir and the other branch is carried to a lower point than the entering end of the pipe and empties into struck out to provide passages through the wall and with the struck out portions constituting guards integral with the wall and in overhanging relation to the passages, a valved supply pipe leading into the compartment, and a float in the compartment s controlling the valve.

In testimony, that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
